authorization to change other users passwords,
use passwd command

Subject: Re: asroot passwd: not authorized
SCO uses "asroot" to have the functionality of "sudo". You can
use sudo on SCO systems but the built-in method is "asroot" and the
various kernel authorizations that go with it. For certain tasks,
like controlling printers or changing passwords, a user can be
given specific power for those functions. For example, to run
passwd, the user needs "auth" authorization (and doesn't need
"asroot" at all), which will let them run passwd for any other user
that does NOT have "auth" authorization. The idea behind this is
that this user can change other users passwords, but not root's, or
that of any other user who has been granted this power. It would be
a major danger to do this any other way.
This is a good example of giving partial power without full root
See How can I make a
shell script setuid so that ordinary users may use root privilege
Unixware uses tfadmin for similar functionality: uw7 root privileges sudu
If you'd rather use sudo: Basics: Using sudo,
SUDO on SCO, syslog.conf uses TABS
prior to 5.0.6.
There are people who feel that no one should ever have direct
root access, that all system maintenance should be done through
sudo or something like it. Apple's Mac OS X largely follows that,
and I'm not uncomfortable with it though I do have some
reservations: sudo vs. root
See "man authorize"

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.
Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
